Abstract:
An automatic analyzing apparatus which can make an adjustment to a target temperature so as to stabilize the light intensity of an LED and also can make the adjustment to that temperature in a short time is provided. The automatic analyzing apparatus in which an LED is used for a light source 114 includes a temperature adjusting mechanism 201 for the LED, and the temperature adjusting mechanism 201 includes a metal member 202 provided with the light source 114, a pair of metal pipes (water-flowing pipes) 203 buried in the metal member 202 and allowing constant-temperature bath water to flow therein, and pins (small metal piece members) 204 bringing only a heat-generating lead 252 of the light source 114 into direct contact with the metal member 202. Therefore, the temperature adjusting mechanism 201 can make an adjustment to a target temperature so as to stabilize the light intensity of the LED, and the adjustment to that temperature can be made in a short time.
Abstract:
A system and method are described herein for self-referencing a sensor that is used to detect a biomolecular binding event and/or kinetics which occur in a sample solution flowing along side a reference solution in a micron-sized deep flow channel.
Abstract:
PROBLEM TO BE SOLVED: To provide a transmission concentration device capable of reducing an environmental temperature effect, which prevents an error due to a temperature difference from arising, by bringing the temperature of a concentration sensor to coincide with that of a fluid in a fuel cell. SOLUTION: The concentration device is installed mainly at a fluid communication space 12a of a fluid circulating apparatus 12 in a fuel cell system, wherein a light signal output from a light source device 22 is projected onto an optical sensor 21a through the fluid in the fluid circulating apparatus 12, and the optical sensor 21a outputs an electric signal corresponding to a fluid concentration to an arithmetic unit, and the fluid concentration in the fluid communication space 12a of the fluid circulating apparatus 12 is calculated based on the electric signal output from the optical sensor 21a and an electric signal output from a temperature sensing unit 4.
